We're getting ready (as soon as the oppressive heat breaks) to run permanent power & water lines to the barns. I'd LOVE to put in a full nipple water system, but not if I can't freeze proof it. I found this system http://www.bassequipment.com/Waterers/Freez-X,+Thermocube+/default.aspx but it's not going to be anywhere near big enough for us~LOL We usually have mild winters, but last year we had a week of 0-15 degree temps and about 2 straight months where the snow never melted. I don't want to be stuck with ice and a flood in frigid weather. Any ideas or photos, photos would be awesome! Thanks so much in advance!
